Improving the electrocatalytic properties of Pd-based catalyst for direct alcohol fuel cells: effect of solid solution

Abstract The tolerance of the electrode against the CO species absorbed upon the surface presents the biggest dilemma of the alcohol fuel cells. Here we report for the first time that the inclusion of (Zr, Ce)O2 solid solution as the supporting material can significantly improve the anti-CO-poisonin...
